FREQUENTLY ASKED QUESTIONS (FAQ)

What does it mean that the screw is partially threaded?

A partially threaded hexagon head screw has an unthreaded portion of the shank between the head and the thread. This can provide better force transmission and stability in certain screw connections.

When should a partially threaded hexagon head screw be used?

It is used when the joined materials need to be pulled together effectively and where the unthreaded part of the shank is intended to absorb shear loads or provide a better fit in the connection.

What is material class A4?

A4 is a stainless steel with very good corrosion resistance for use in normal outdoor environments, damp environments, and many industrial applications.

Is DIN 931 the same type of product as ISO 4014?

Yes, DIN 931 is essentially equivalent to ISO 4014. Both standards refer to hexagon head screws with partial threading.
